BAND-CUT]?TER AND FEEDER FOR THRESHERS.

Patented July 30, 1907.

Application filed April 16, 1906. Serial No. 311,840.

To all whom it may concern:

Be it known that we, THOMAS S. PEARSON and Vre'roe VATLE, citizens ofthe United States, resid ing in Clay township and Center township,respectively, in the county of I-Iowardand State of Indiana, haveinvented new and useful Improvements in Band- Outters and Feeders forThrcshers; and we do declare the following to be a full, clear, andexact description of the invention, reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon, which form a part of this specification.

This invention relates to automatic feeders and band cutters which areadapted to be used in connection with various types of machines that aredesigned to separate grain from the stalks on which the grain grows, theinvention having reference more particularly to band cutters and feedersfor grain separators or threshers of well-known construction.

Objects of the invention are to provide improved apparatus whereby thebinding twine or band s. which are used to form sheaves of grain may becut, and whereby the sheaves may be broken up and spread out and fedevenly to the cylinder of the separator; to provide improved frames forthe apparatus, and to provide feeders that may be relied upon to operatewithout becoming choked.

With the above-mentioned and minor objects in view the inventionconsists in feeding apparatus and band cutters mounted thereon,constructed and arranged in a novel and advantageous manner, which willbe fully described hereinafter; and, further, the invention consists inthe novel parts and thecombinations and arrangements of parts ashereinafter particularly described and claimed. 7

Referring to the drawings, Figure l is a side elevation of the feedingand band-cutting apparatus constructed substantially in accordance withthe invention and shown in connection with a separator in fragmentaryside elevation; Fig. 2, a top plan thereof; Fig. 3, an elevation of oneof the main feed rolls detached from the machine; Fig. 4, a transversesectional view of the apparatus on the plane of the line A-A in Fig. 2;Fig. 5, a fragmentary transverse sectional view on the plane of the lineBB in Fig. 2; Fig. 6, a fragmentary vertical sectional view on the planeof the line CO in Fig. 5; and, Fig. 7, a fragmentary longitudinalvertical sectional view on the plane of the line D-D in Fig. 5.

Similar reference characters in the different figures of the drawingsdesignate corresponding elements or features.

In the drawings a designates a separator or thresher;

. Z) the cylinder thereof; 0, the cylinder-shaft, and c the drive pulleyof the cylinder-shaft.

Practically embodied, the improvement comprises a main frame E whichmaybe connected to a separator in any suitable manner so that one end ofthe frame may be supported by the separator frame near the eylinder b towhich the grain is to be fed, the other end having legs 8. The mainframe comprises a table (I and side-members, there being rollers e and fmounted in the frame at the ends of the table, and belts 9 havingflights h attached thereto extend about the rollers and across the tablecomprising parts of the main feeder conveyer, together with a feed rollF having fingers 9 and mounted rotatively on the main frame; The roller0 has a shaft 1' to which is attached a gear wheel 7' that is in meshwith a pinion k which is secured to the shaft 0 of the cylinder b, fordriving the main feeder, and the roll F has a shaft Z to which isattached a gear wheel at that meshes with a gear wheel n which issecured to the shaft i for driving the roll F.

A rotative shaft 7) is mounted upon the frame E and has a sprocket wheelq attached thereto on which is a chain belt 10 that is connected to asprocket wheel r which is secured to the shaft of the roll F, the shaftq having a pair of worm wheels s and 8 attached thereto.

The main feeder is provided with apparatus for cutting the bands of thesheaves of grain and delivering and spreading the grain in stalks on theconveyer of the main feeder, the apparatus comprising twin conveyers andband cutters arranged at opposite sides of the main feeder, although insome cases only one conveyer and band cutter may be provided. Inconstructing this apparatus, a pair of beams G and G, preferablycurvedas arches, are attached to the main frame E and span the table (1thereof, there being a cap beam 11 attached to the tops of the beamsextending from one to the other beam, and a series of fingers t areattached to the cap beam 1]. and, extend at inclined angles toward thetable d and the separator. Two pairs of feed rolls, H and I, and II andI, are journaled on the beams G and G and are provided with peripheralprojections 12, the rolls I and I being preferably springpressed eachtoward its companion roll. The roll H has an extended shaft u to whichis secured a gear wheel 12 that is in engagement with the Worm 8, therebeing also gear wheels 10 and :0 attached to the shaft of the roll. Theshaft u of the roll H also has a gear wheel 1 attached thereto that isin engagement with the worm 8, other gear wheels w and :20 beingattached also to the shaft of the roll H. A gear wheel y is attached tothe shaft of the roll I and meshes with the gear wheel as, and a gearwheel y is attached to the shaft of the roll I and meshes with the gearwheel at. The two pairs of feed rolls are designed to break up andscatter the grain stalks onto the main feeder conveyer.

Conveyer frames J and J are connected to the sides of the main frame E,one at either side, and are provided with suitable legs 2 that supportthe outer endsof'the frames, the inner ends of the frames beingpivotally supported, so that the frames may be adjusted to differentangles of inclination. Rollers K and L are journaled in the frame J, andsimilar rolls K and L are journaled in the frame J, the frames beingprovided with tables M and M. Each frame, J and J is pivoted by means ofsuitable brackets 13 that are attached to the main frame E, the shafts14 of the rolls K and K extending through the brackets and serving aspivots for the frames. Conveyer belts 15 having flights 16 are mountedon the pairs of the rolls of the frames J and J, these frames having endgates 17 for holding the sheaves temporarily until removed by theconveyer belts.

An elevated bridge N is mounted upon the frame J, and a shaft 0 ismounted rotatively on the bridge, upon the bridge there being also aband cutter P suitably mounted rotatively. On the frame 'J is a similarbridge N supported a shaft 0 and also a band cutter P. The band cuttersmay be variously formed, and preferably operate above the rollers K andK. The shafts O and 0 each have a bevel gear wheel 18 and also a spurwheel 19 attached thereto, the latter being at the ends of the shaftsand engaged by idlers 20 that are mounted on the frames J and J, theidlers being engaged by gear wheels 21 that are attached to the shafts14 of the conveyor rolls. Gear wheels 22 are mounted on the beam G andconnect the wheels 21 with the gear wheels to or w. The band cutters areprovided each with a bevel gear wheel 23 that engages the wheel 18 ofthe shaft O or O.

In practical use when the separator is in operation the roller 0 will bedriven by the gearing described, and the mechanism of the feeder andband cutters described above being connected with the roller 6 willconsequently be driven also. The sheaves of grain are to be placed uponthe conveyer belts of the frames J and J and will thereby be carriedunder the shafts O and O to' the band cutters P and P by which thebinding twine will be severed, the sheaves also being divided somewhatby the knives of the band cutters. The straws or stalks will then passbetween the pairs of feed rolls H and I, or H and 1, onto the conveyerthat runs on the table d in loose spread out order, and in case of toorapid feeding momentarily, the accumulation of stalks would be forcedagainst the fingers t, and would be retarded thereby so as to becomespread out before advancing to the feed roll 1* which will assist theflights h in feeding to the cylinder 1) of the separator.
